Hmmm. If what you’re saying is that one is art and the other isn’t based on what it sells for, I definitely can’t get on board with that.
Some artists are better than others - that’s undeniable. But Keane and Rembrandt are both artists in my book.
I heard many years ago the phrase “learning to draw is not a matter of learning to draw - learning to draw is a matter of learning to see.” This, to me, is one of the things at the heart of art. In its various forms, it is created by those who have learned to truly see, and have taken the time to do so. This skill and mindset can be applied to leatherwork as much as to oil paints.
